ViST: A Dynamic Index Method for Querying XML Data by Tree
... Figure 5 shows an example of using a suffix-tree-like structure to index structure-encoded sequences for non-contiguous matching. We insert two sequences, Doc1 and Doc2 , into the suffix tree. Originally, the elements in the sequences represent nodes in the XML document trees, from which the sequenc ...
